# Get Dimension This function block returns the dimensions of an input image as a list. It is useful when you need to know image width, height and channel information before applying other image operations. ## đŸ“Ĩ Inputs `Image Any` This input accepts any image data from other function blocks. ## 📤 Outputs `Dimensions` Returns the image dimensions (for example: height, width, channels) as a list of numbers. ## 🕹ī¸ Controls This function block has no controls. ## đŸŽ¯ Features * Quick retrieval of image shape information to guide downstream processing. * Works with color and grayscale images; output reflects the image shape format provided. ## 📝 Usage Instructions 1. Connect an image-producing block (camera, loader or processing block) to the `Image Any` input. 2. Read the `Dimensions` output to get the image shape information. 3. Use the dimension values to configure other blocks or to validate image sizes in your scenario. ## 📊 Evaluation When evaluated, this block inspects the connected image and outputs a numeric list describing its dimensions (e.g., height, width, channels). If no image is provided, no dimension list will be produced. ## 💡 Tips and Tricks * Use `Load Image` or camera input blocks such as `Camera USB` and `Camera IP (ONVIF)` as image sources to quickly check incoming image sizes. * If you need to preview the image before checking dimensions, attach a `Show Image` block to the same image source. * To measure a cropped region, connect a cropping block like `Image ROI` or `Image ROI Select` before this block — the `Dimensions` output will then reflect the cropped area. * When working with very large images, consider feeding a resized version using `Image Resize` or `Image Resizer` before asking for dimensions to speed up downstream processing. * Use `Image Resolution and Channel Value` if you also want separate width/height/channel outputs or more detailed channel information. ## 🛠ī¸ Troubleshooting * No output or empty result: ensure an image source is connected to the `Image Any` input. * Unexpected number of elements in the result: some images are grayscale (height, width) while color images include a channel count (height, width, channels). Use `Split Image` or `Image Resolution and Channel Value` if you need per-channel information. * If the input may occasionally be missing, use blocks like `Is None` or `Replace None` upstream to provide fallback data and avoid interruptions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.augelab.com/function-blocks/image-transformations/analysis/get-dimension.md?ask= ``` The question should be specific, self-contained, and written in natural language.
